"Bought a set with this in, to use with my own creations. The apps wouldn’t let me run 2 simple motors manually, had to use a third party app. Ideally I need a physical speed remote control, as I can’t use my phone to take videos. I don’t think price tag is justified, it isn’t even rechargeable! Waste of money, I’ll stick to power functions until Lego start listening to the customers concerns."
